The casting manner due to the bidirectional pulling removal die horizontal continuous caster and is used the electromagnetic churning device

摘要

PURPOSE:To enable castings at the same time into plural strands and to reduce the casting cost by arranging electromagnetic stirring devices just below each feed nozzle and at side part of each mold and stirring molten metal under the specific flow velocity. CONSTITUTION:Plural strands are set as parallel approaching to longitudinal direction, and the mold 6 for each strand is independently set or uses a long wall side 6A and short wall side 6B in common. Into the mold 6 for each strand, the molten metal 2 is poured from each of the independent feed nozzles 8A, 8B in a tundish 4 for common use, respectively. An oscillation device 10 and cast billet drawing device 14 for each mold 6 are cooperated with the other mold to execute the same control. In each mold 6, the electromagnetic stirring devices 18A, 18B are arranged at outside just below center part of the mold and at side wall of the mold respectively, and by stirring the molten metal 2 at center part of the mold under at least 20cm/sec flow velocity, separating point for each strand is possible to control to =50mm the max. displacement just below the feed nozzle 8A, 8B, and adverse effect to the quality of the cast billet is not exerted.
